Hot Rolled Steel C1045
Grade Summary: Medium carbon steels suitable for machining, forging, heat treating, cold drawing, etc. When heat treated, 1045 provides greater strength than can be obtained from lower carbon steels. Grade C1045 can be hammer forged, machinability is good, but forming and welding qualities are limited.
Typical Applications: Axles, machinery parts, stud bolts, ordinary shafts, pinions, gears, rock screens, forming dies, tool shanks.
Available products: Round Bar,Shafting Square Bar and Plate.
